| CVE | Severity | CVSS | Published | Summary |
|---|---|---|---|---|
| CVE-2026-70469 | HIGH | 7.5 | Sep 16, 2026 | Apache NiFi 2.11.0 disabled support for gzip-encoded HTTP requests for the application REST API and rejected requests that included the standard Content-Encoding header indicating gzip encoding. The framework enforcement filter did not check multiple instances of the Content-Encoding header and did not reject non-standard identifiers for gzip encoding, allowing a malicious client to send crafted requests that could consume excessive amounts of memory. Upgrading to Apache NiFi 2.12.0 is the recom |
| CVE-2026-87976 | HIGH | 7.2 | Sep 16, 2026 | Apache NiFi Registry 0.4.0 through 2.11.0 are subject to path manipulation when storing extension bundle content using group, artifact, and version coordinates from uploaded NAR manifests. The default file persistence provider used coordinates as filesystem path components without rejected parent-directory names, and the path-containment check compared an unnormalized resolved path. An authenticated user authorized to write and delete bundles in a bucket can upload a NAR with a crafted manifest |
| CVE-2026-82561 | MEDIUM | 5.9 | Sep 16, 2026 | Apache NiFi 1.5.0 through 2.11.0 provide REST API methods that replace the entire contents of a Process Group using a client-supplied flow definition, covering Process Group flow replacement together with versioned flow update and rebase operations. Framework authorization for these methods was limited to read and write privileges on the Process Group itself, unlike the corresponding asynchronous update request methods, which also authorize the components encapsulated in the Process Group along |
| CVE-2026-86089 | LOW | 2.3 | Sep 16, 2026 | Apache NiFi 2.11.0 supports migrating the contents of a version-controlled Process Group into a Connector using REST API methods that list eligible migration sources and submit migration requests. The framework authorized both methods against the target Connector alone, without evaluating access to the Process Groups involved. The absence of Process Group authorization allowed an authenticated user with read access to a Connector to enumerate the identifiers, names, and flow registry details of |
| CVE-2026-81866 | LOW | 0.5 | Sep 16, 2026 | Apache NiFi 2.9.0 through 2.11.0 provide Connector configuration update and verification REST API methods that do not enforce authorization checking on Assets and Secrets referenced in proposed configuration. Updating or verifying a Connector configuration step can apply Asset and Secret references, but framework authorization was limited to write privileges on the Connector itself. As a result of the missing authorization, an authenticated user authorized to modify a Connector, but not authoriz |
